Skeleton Has Mechanical Bones
ALL honors for devising a novel way to attract trade go to a manufacturing concern in Hartford, Connecticut. The stunt they performed was the construction of an amazingly realistic skeleton from parts turned out at the plant. The creation is shown above. You will have to look closely to see that it does not have real bones.

Alcohol No Danger to Kidneys Alcohol No Danger to Kidneys THE traditional idea that alcohol is bad for the kidneys, the heart and arteries, is exploded by experts of the American Medical Association.

Perform These STARTLING STUNTS with DRY ICE
by DALE R. VAN HORN
Dry ice, which might be called frozen carbon dioxide, lends itself to the performance of some mysterious and startling stunts. As told in this article, it will fire off a toy cannon, propel a model boat, make a spoon squeal like an assassinated pig, and cause a rubber band to writhe as in a terrible spasm of pain.
DRY ICE, or carbon dioxide in solid form, is an exceedingly interesting substance. We know it best as the gas that adds sparkle to our drug fountain drinks. But as a solid, it's something else again, unique in several ways. For instance, carbon dioxide cannot exist as a liquid at normal atmospheric temperatures. It must be either a gas or solid. Only at temperatures below 31 degrees Centigrade can it exist as a liquid.

Washing Machine Motor Drives Midget Auto 12 M.P.H.
IT MIGHT be small and funny looking but it goes places, does the little midget car built by Stanley McCrary, of Seattle, Washington.
In building his somewhat diminutive auto, Stanley waylaid an old washing machine and made away with its motor. When he came to the problem of providing a clutch and steering gear, he simply made them in his own workshop. As to the gas tank, well you can see for yourself in the photo at the left.

Build a 75 Foot TARGET RANGE in Your Basement
A lot of wide open space isn't necessary for the construction of a target range. By following plans given here you can build a 75-ft. range in your own basement for practice shooting.
RIFLE enthusiasts who keep regular business hours may find it inconvenient to enjoy anything approaching regular shooting practice. Some may belong to various clubs which hold night sessions at indoor ranges, while a few possessing extensive grounds may have their own private target ranges, but the average sportsman with small bore rifle equipment and a strong desire to shoot is not likely to have such facilities available to him.

ICE-ISLAND in Mid-Atlantic Proposed
SEADROMES for ocean landing fields are not a new idea, a steel 'drome designed by Edward Armstrong, recently described in these pages, being well on the road to practical acceptance. But the proposal to build seadromes of ice, recently advanced from Germany, seems fantastic until one realizes that the idea has already passed the experimental stage with flying colors.

How Much Longer Will Our Big Cities Last?
Like the dinosaur, which grew too bulky for its own good, our mammoth cities are doomed to extinction, say scientific prophets. Disintegration began when Lindbergh hopped the Atlantic, foreshadowing the day of interurban planes, as told here.
by RUSSELL J. MORT
SCIENTIFIC prophets looking into the future proclaim that our mammoth cities, the likes of which the world has never seen before, are doomed to obsolescence. In time, cobwebs will enshroud the cloud-piercing Empire State building and dandelions will grow on Fifth Avenue and Wall Street, they believe, after exhaustive studies into the trend of the times.

Plane Passengers Bailed Out Automatically
ONE of the most pressing needs of aviation has been a mechanical method whereby all passengers could be simultaneously and automatically bailed out at the psychological moment, that is, when the pilot learns that all hope for saving the plane is lost.
Such a method has now put in its appearance in the aviation world. With the equipment shown in the above photo, it is possible for the pilot to send his passengers on a flight groundward by parachute whether they want to bail out or not.

Iceless "Ice Box" Lowered in Ground Keeps the Food Cool
A COUNTERWEIGHT on one end, and a cylindrical container on the other end of a steel rope running over two pulleys supported on a pole, makes up the major portion of an ingenious contrivance for cooling foods.
The container, shown in the accompanying photo, fits loosely into a seven-foot hole in the ground lined with a steel casing. It has three shelves, and a door closes it off from the outside. Three iron rods about four feet long run from the top of this "cooler" container to the sustaining end of the rope or cable.

The Fascinating Story of Your Motorbike

Adopted by the police, the modern version of the powered bike forms the backbone of the speed laws and strikes terror into the hearts of gangsters. This authoritative article tells you some startling facts about the birth, growth and present status of the motorbike.
